tim m biet
a) (x^2-x+1)x-(x+1)x^2+m= -2x^2+x+5
b) -x^2(x^2+x+1+2)= -x^4-x^3-x^2+m
giup vs nhanh mk dag can gap
tim x biet
a) 4(x+1)^2-9(x+2)^2=0
b) 4(x+1)^2+(2x-1)^2-8(x+1)(x-1)=11
giai cach lam giup minh nha
Tim x Biet ( x + 2 )2 -6x-12=0
ai giup mik dc ko a
ai giup minh vs
tim x biet
(3x+2)(2x+9)-(x+2)(6x+1)=x+1-(x-9)
Tim x, biet:
a)(x-3)^3-(x-3)(x^2+3x+9)+9(x-1)^2=15
b)(x^2-2)^2+4(x-1)^2-4(x^2-2)(x-1)=0
Giup minh voi!
Tim x , biet
(2x-1) ^2 + (x+3)^2 -5(x+7)(x-7) = 0
moi ng lam nhanh giup ! Thanks
tim x de A thuoc Z biet A=x^2-3x+1/x+1 .Moi nguoi giup minh giai bai nay trong trua nay nha
Tim x va so tu nhien n, biet:
x2 + 2x + 4n - 2n+1 = -2
giai nhanh giup minh nha, minh dang can gap ! THANHS nhiu!
Rut gon a biet a=(x^2-2x/2^2+8+2x^2/8-4x+2x^2-x^3)x(1-1/-2/^2)
Ai giup minh minh tick nha ::)))
